To au wle/m, it may concern:

Be it known that I, JOHN BLAs1Us,a citizen of the United States, residing at Union Hill, in` the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Sash-Locks, of which the following is a full and complete specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to sash-locks for window-sashes; and the object thereof is to provide an improved will lool; the sashes together when in their closed position and which will also draw said sashes together at their meeting-points, the operation of the device being automatic; and with this and other objects in view the invention consists in the construction, combination, and arrangement of parts hereinafter described and claimed.

The invention is fully disclosed in the followingspecication,'of which the accompanying drawings form a part, in which- Figure 1 is a sectional plan view showing my improved sash-lock connected with the lower part of the upper and the upper part of the' lower sash; Fig. 2 2 of Fig. 1; Fig. 3, a section on the line 3 3 `of Fig. 1, and Fig. it a bottom plan view of that part of the lock which is connected with the lower sash.

In the drawings forming part of vthis speciiication the separate parts of my improvementare designated by the same numerals of reference in each of the views, and in said drawings I have shown at 5 the lower part'oi the upper 'sash and at 6 the upper part of the lower sash, and in the practice of my invention I provide a sash-lock comprising two parts, one of which is connected with the lower part of the upper Asash andthe other with the upper part of the lower sash.

That part of the device which is connected with the lower part of the upper sash consists of a base-plate 7, having end projections by which it is screwed to the sash, as shown at 8, and said plate 7 is provided centrally with an upwardly-directed portion 9, and the forward portion of the said plate and said upwardlydirected portion 9 thereof are hollowed out to device of this class which 2, a section onv the line form a `chamber 10, and said upwardly-divv rected portion 9 of' the plate 7 isprovidedwith rounded or beveled sides and top corners, as shown at 11, between which at the top is an open notch or recess l2 and in the sides of which are notches or recesses 13.

That portion of the' device which is connected with the lower sash comprises a bottom frame 14, having side plates or projections by which it is screwed to the sash and in which is formed a central transverse slot or opening 16, above which is placed a rectangular plate 17, which is shown in section in Fig. 3, the position of which is shown in dotted lines in Fig. 4, and said plate 17 is provided with a thickened rear portion 1S, whichpasses downwardly through the slotor opening 16 in .the frame 14 and which is provided at its rear end with a downwardly-directed transverse lug or projection 19, and adjacent to the rear edge of the plate 17 is au upwardly-directedpin 20.

Placed below the slot or opening 16 in the frame 14C and transversely of said slot 4is a small rectangular plate 21.and in said slot or opening 16 in the frame 14 and held therein by the plate movable plate 22, having at its outer end an arm 23, which projects through the side of the frame 14 and is provided with a handle 24. A top plate 25 is placed over the frame 11i and provided with a downwardly-directed front 26 and a downwardly-directed back 27 ,l

and centrally of said 'top plate 25 is formeda ldownwardly-directed pin 28, the lower end of'which is screw-threaded, and the pin 28 passes through the plate 17, through the slot or opening 16 in the frame 14, and through the small rectangular plate 2l andis provided on its lower end with a nut 29, by which the parts are held together. y

The small movable plate 22 in the slot or opening 160i the frame 14 may be moved outwardly or inwardly by the handle .24, and said plate is provided at its inner corner adjacent to the pin 28 witha notch or recess through which said pin passes, and the position of the top plate 25 may be adjusted toward or from the upper sash by moving the plate 22 outwardly or inwardly, and in order 21 and the plate 17 is a small ICO 'to do this the screw 29 must be manipulated so as to loosen the parts and again tighten them together, the object of this construction being to adapt the device to different conditions of thc sashes. The top plate is also provided near its rear edge with a downwardly-directed pin 39, which corresponds with and cornes in Contact with the upper end of the pin 20, and mounted on the pin 20 is a spring 3l, having forwardly-directed arms 32, each of which is provided at its f ront end with an upwardly-directed extension 33, and

the object of the 3l on the pin 20.

A triangular slide 34 (shown in full lines in Fig. 3 and in dotted lines in Fig. l) is mounted on the plate 17 and provided with side arms 35, between which the pin 2S passes, and the outer sides of the arms 35 are beveled outwardly, and said slide 3i is provided with a forwardly-directed shank 36, having a knob or head 37.

Pivoted beneath each side of the top plate 25, as shown at 3S, is a bolt 39, and the outer ends of the spring-arms 32 force the front ends of said bolts outwardly and the rear ends thereof inwardly into the notches or re cesses 13 in that part of the device connected with the upper sash, and said bolts are provided at their front ends with laterally-projecting knobs 40.

The normal position of the parts is that shown in Fig. l, in which the sashes are locked together, and in order to raise the lower sash and lower the upper sash the front ends of the bolts 39 are pressed inwardly against the operation of the spring-arms 32. This releases the rear ends of said bolts from the notches or recesses 13, when the position of the sashes may be adjusted as desired. Suppose the upper sash to be at its highest position and the lower sash raised. If the lower sash be lowered,the rear ends of the bolts 39 will strike the beveled surfaces ll of the raised portion of that part ot' the device connected with pin 30 is to hold the spring the upper sash and will pass down over said beveled portions and will be forced into the notches or recesses 13 by the spring-arms 32 of the spring 30, this operation being automatic and resulting in locking the sashes together, and whenever it is desired to raise the lower sash or lower the upper sash the forward ends of the bolts 39 are pressed inwardly, so as to release the rear ends thereof from the notches or recesses 13. By drawing the slide 34E outwardly the side arms thereof will press against the upwardly-directed pins or extensions 33 of the spring-ar1ns 32 and prevent the bolts 39 from being operated, this operation resulting in locking the device so that the sashes cannot be separated.

The top plate 25 of that part of the device connected with the lower sash is provided centrally with an upwardly and backwardly directed arm 4l, having a downwardlyhdirected extension 42, the inner surface of which is beveled and adapted to engage with 'the upwardly and forwardlyinclined portion 9 of the plate 7, the object of this construction being to draw the sashes together when the lower sash is lowered or the upper sash raised, and thus prevent drafts from passing between the adjacent parts of said sashes.

My improved sash-lock is simple in construction and operation and well adapted to accomplish the result for which it is intended, and it will be apparent that changes in and modifications of the construction herein described inaybe made without departing from the spirit of my invention or sacrificing its advantages.

Having fully described my invention, I claim as new and desire to secure by Leiters Patent-n A sash-lock, comprising two parts one of which is adapted to be secured to the upper sash, and the other to the lower sash, that part which is adapted to be secured to the upper sash being provided` with an upwardly `and forwardly `directed portion having a notch or recess at its top, and side notches or recesses, and that portion which is adapted to be connected with the lower sash being provided with pivoted spring-operated side bolts which are adapted to swing laterally, and the rear ends of which are designed. to enter said side notches or recesses, said last-named part being also provided with a backwardly-directed arm having a downwardly-directed extension, and means for locking said bolts, the upper portion of that part which is adapted to be secured to the lower sash being adjustable toward or from the upper sash, substantially as shown and described.

In testimony that I claim the foregoing as my in vention I have signed my naine, in presence of the subscribing witnesses, this 2d day of November, 1898.

JOHN BLASIUS.
